       GPT wants an extra partition. And I made mine too large

/dev/sda2  511M  5.3M  506M   2% /boot/efi

If you need to blow up your HD partition, I suggest you to use dd to
write junk in the first few sectors. it can be as simple as (assuming
drive is sda)

dd if=/dev/urandom of=/dev/sda bs=1024m

and let it rip for 20s before cancelling it.
